The Eco1800S Solar Generator includes a 12V DC power port for operating
common DC auto accessories up to 12 amps from the internal 12-volt
battery. If the 12V DC power port is overloaded a protective internal
breaker will open (interrupt) current flow. When the overloading accessory
is disconnected, the breaker will automatically re-close (reset) within a
few minutes.
12V DC POWER PORT
NOTE: The PVCC operation description assume a continuous adequate
level of PV energy available to the PV Charge Controller. Due to the
potentially variable output of a solar panel due to changing weather and
panel’s orientation to the sun, the charge algorithm/time may be extended,
stopped, restarted without notice. If sufficient charge capacity is not
available from solar source, connect the Eco1800S Solar Generator to
120 VAC utility power to allow the AC five-amp charger to assist in
completing the battery charge.
IMPORTANT: When powering the 12V DC accessory, do not allow the
Eco1800S Solar Generator internal battery to be discharged completely
(i.e., 0% state-of-charge) which can permanently damage the internal battery.
To avoid over-discharging the internal battery, do not leave any DC accessory
including mobile phone chargers or other portable appliances permanently
connected to the Eco1800S Solar Generator’s 12V DC power port.
See also Warning below.
NOTE: The Battery Charge (%) reading on the top panel display
(when turned on) is only accurate after the Eco1800S Solar Generator
internal battery has been resting (not charging or discharged) for at least
30 minutes.
The PVCC will initiate a new charge cycle when solar input energy is first
connected and there is sufficient energy to activate it. The PVCC includes
Pulse Width Modulation (PWM) circuitry that accepts input energy to
charge up to 8amps until reaching 14.4–14.8 volts (battery), then maintain
this absorption voltage for four hours, then finally transfer to float mode
attempting to maintain 13.5volts. While in float mode, if the battery voltage
drops below 12.5volts, the charger will initiate a new charge cycle
(provided there is sufficient PV Solar energy available).

UNDERSTANDING ERROR CODES
If the products connected to Eco1800S Solar Generator do not operate and
the alarm is sounding, check the Eco1800S Solar Generator top display LED
screen for an error code.

E04
Low voltage shutdown
because battery is
discharged.
Overload shutdown
while supplying backup
power. The AC product(s)
connected are consuming
more than Eco1800S
Solar Generator’s power
rating.
Over-temperature
shutdown has occurred.
Eco1800S Solar Generator
has overheated due to poor
ventilation, excessive
ambient temperature, or
power demand beyond the
unit’s output power
capability.
Disconnect products from the AC
outlets. Allow the unit to cool for
20 minutes. Clear blocked fan or
remove objects covering unit. Move
the unit to a cooler place. Reduce
load to less than 1800W if
continuous operation is required.
Use products with a total power
consumption within Eco1800S Solar
Generator’s continuous power
rating of 1440W.
Use products with a total starting
surge power within Eco1800S Solar
Generator’s capability of 2880 W.
The AC products
connected have a surge
power that exceeds
Eco1800S Solar Generator’s
surge capability.
One or more of the
connected products are
damaged.
Have the damaged product serviced
by a qualified technician.
Recharge battery by plugging the
AC power cord into a wall outlet.
